Answer:
Option A, light energy from the sun
Explanation:
In the process of photosynthesis, the energy from sun in the form of light and heat is taken to undergo glycolysis and prepare glucose/starch (chemical).
Thus, the light and heat energy of sun is converted into the chemical energy.
Option B and C are incorrect because no kinetic energy or chemical energy is taken from any source.
Option D is also incorrect because heat is taken but it is not taken from the surrounding environment. The source of heat energy is sun.
Thus, only option A is correct
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
Answer 0.5
when reporting calculations from sig figs, report the number of sig figs in the least accurate measurement
so
((2.0265-2.02)/2.0265) x 100.00
((2.0265/2.0265) - (2.02/2.03)) X 100.00
(1.0000 -0.995) X 100.00
0.005 X 100.00
0.5
I am sure it is DNA polymerase.
I'm a bio major, hope I helped :)
Answer:
C. Magnetization of iron
Explanation:
This is a chemical change and cannot be undone by physical means therefore it isn't a physical change
